Description
Technical field
The present invention relates to the hot-working process of metal material, relate to the technology equipment of the cast form of high-abrasive material medium, specifically, relate to a kind of rising head and casting mold cavity integrated molding mould.
Background technology
Along with the technical merit of melting and casting industry improves constantly, considerable part mechanization or intelligent production line are progressively applied to melting and casting industry, replace manual work.In the Foundry Production mode of especially horizontal parting, dead head technology is still in handwork level segment, seriously constrains the development of mechanization or intelligent production line.
Dead head is one of requisite technique of melting and casting.At present in melting and casting industry, several manufacture methods that dead head makes shaping usual employing are:
1, adopt damp film sand by easy wooden model or metal mould forming, damage is large.
2, adopting water-glass sand, to realize dead head by easy wooden model or metal die shaping, or shaping by back-up sand in metal mold dead head mould bases, need to the heating of dead head sand mold or baking-curing shaping.
3, resin sand is adopted to realize dead head by metal die shaping, or shaping by back-up sand in metal mold dead head mould bases, and in forming process, constantly heating makes it solidify.Shaping in order to realize dead head, need to add separately a core shooter, its dead head mould structure is complicated, and the comprehensive method of investment is large.
Above-mentioned several dead head makes, and workload is large, more needs prefabricated and storage in advance, needs to install one by one during use.Be easy to cause the damage of dead head to there is waste in carrying, installation process, more easily produce a large amount of loose sands during installation, necessary cleaning must be carried out, take time and effort, particularly loose sand cleaning is not thorough, can be brought into running gate system, directly affect cast article quality during cast by molten metal.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of rising head and casting mold cavity integrated molding are provided, overcome rising head carrying and the defect existed is installed, time saving and energy saving, cost is lower, and can ensure rising head and the casting mold cavity integrated molding mould of cast article quality.
To achieve these goals, the technical solution used in the present invention is:
This rising head and casting mold cavity integrated molding mould, comprise core shooter, casting mould patrix and the forming panel with the mould assembling of casting mould patrix, the nozzle of described core shooter is connected with the core shooting hole of casting mould patrix, also comprise the rising head molding sleeve be located on described casting mould patrix, be provided with end cap on described rising head molding sleeve top; Described casting mould patrix is established the nib communicated with described rising head molding sleeve trepanning; Also comprise the upper core be located in described trepanning and the lower core be located on described forming panel, described upper core top stretch out described end cap and be fixed on core shooter penetrate on head, described upper core bottom and described lower core top are stretched into respectively in nib or trepanning and are connected.
Core bottom end face is provided with detent on described, establishes on described lower core top the positioning step matched with described detent, described upper core and lower core to be matched with positioning step by detent and dock.
The area of the butt end that described lower core docks with upper core is not less than the contact surface that described lower core contacts with described upper core.
Described nib is located at the center of described casting mould patrix, and the center line of described rising head molding sleeve, described casting mould patrix, described upper core and described lower core overlaps.
Described upper core inner is cavity structure, and core bottom center is provided with the aperture reducing self temperature distortion on described.
On described rising head molding sleeve and described Xia Xin center be equipped with bottoming hole, in described bottoming hole, be provided with electrothermal tube.
Described end cap is provided with air discharge duct; Described air discharge duct is circumferentially uniformly distributed at end cap; The air discharge duct of described end cap or described end cap is provided with venting plug.
Be provided with groove penetrating on head of described core shooter, described upper core top is fixed in described groove by locking nut.
Described end cap is structure as a whole with described rising head molding sleeve or described end cap be fixed on together with described upper core core shooter penetrate on head or described end cap is structure as a whole with described rising head molding sleeve and end cap is fixed on penetrating on head of core shooter together with described upper core.
Cavity between described upper core and lower core and described trepanning and nib forms rising head forming recess.
The invention has the advantages that: this rising head and casting mold cavity integrated molding mould, first, rising head and casting mold cavity integrated molding, like this when cast article, do not need to install rising head separately, just do not need carrying and install rising head, can not cause damage to rising head; Can not loose sand be produced simultaneously, not only save loose sand clearance time, time saving and energy saving, loose sand can be avoided the impact of cast article simultaneously, ensure cast article quality.
Secondly, rising head and casting mold cavity integrated molding, only need use the core shooter of casting mold cavity originally to realize, can save cost.
Thirdly, rising head molding sleeve and upper core can realize machine automatization equalization with docking of lower core, while reduction hand labor intensity, can greatly enhance productivity.
Finally, this mould, realizes rising head and casting mold cavity synchronous integrated is shaping, the two synchronous heat curing molding, and process is easy, eliminates the carrying of dead head, installation, directly reduces recruitment, reduces recruitment cost; And it works under meeting heated condition or cold forming work under normal temperature state.
